The DSS14 antenna is the biggest dish

It's their switchboard
它是太陽系里
for every spacecraft in the solar system.
所有飛船的電話交換臺
But all this interplanetary chatter
但這些大量的行星際信息交流
means that Ann can't just pick up the phone to Curiosity

any time she likes.
進行聯系
There's a lot of spacecraft out there,

and they all want to talk back home, too, right?

And so, we have to schedule time at one of these antennas,

like here at DSS14,
預訂時間
and tell the people that we need to talk to Curiosity
告訴工作人員我們需要和好奇號聯系
and this is how long we want to talk to her for,

this guy is already pointed in that direction

and as she comes up, then we're talking.
它一出現 我們就可以聯系了
But a queue for the phone
其他飛船的通信請求
is not the only thing that could kill the conversation

between the rover and the team back home.
